This is not perfectly reliable, as parts can be changed, but it gives you something to go by in combination with the frame details. I'd bet it's early 80's, maybe 1983, give or take, but that's as a non-Guerciotti expert. What makes you believe the pedals are Super Record and not SL? (Crankset is Super Record, BTW, and not Nuovo Record).
